White sweet clover (Melilotus albus Medik.) is a plant species from the group of legumes, and this is why it has a capacity to fix atmospheric nitrogen on the basis of symbiosis with bacteria of the genus Rhizobium that is not available for most plants.The species is used primarily for the production of biomass and for soil remediation. Biomass of white sweet clover can be used in biogas plants. It is also one of important producers of nectar for pollinators. The aim of the experiment was to find out whether the a...

In 2021, a field experiment was conducted with white mustard (Sinapis alba L.) the seed of which is an interesting raw material in agriculture, industry and food production. Stands of tested plants were established without tillage into a freezing catch crop from the Fabaceae family within regenerative agriculture. The stand of clovers was used as a tool of bio-drilling to work the soil and as a source of nitrogen required by the subsequent crop, and the frozen biomass was applied as mulch onto the soil surface. Th...

The aim of the study was to compare variable rate (VRA) and uniform (UNI) application of mineral nitrogen fertilizers in winter wheat and to evaluate the effect on the achieved yields, nitrogen balance and nitrogen use efficiency (NUE). For these purposes, a field experiment with an area of 16.98 ha of winter wheat was established in 2022 at farm Agra Risuty s.r.o. (Czech Republic, EU). Variable nitrogen topdressing was realized twice during the vegetation period based on yield potential (YP) maps. The evaluation ...

The presented paper deals with the targeted application of pre-emergent herbicides. The field experiment was established in 2022 and 2023; two plots sized 26 ha and 30 ha were selected and the accuracy of the application was tested. There were local outbreaks of weeds on selected plots of land, which had to be eliminated before sowing the main crop - soybeans. Both plots were monitored using an unmanned aerial vehicle (UAV) - Mavic 3M with the multispectral camera. After the end of the monitoring, spectral analysi...
